  1. 1. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  3. 2. A high-order artificial viscosity finite element method for the Vlasov-Poisson system

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Junjie Wen; [2023]
    Keywords : ;

    Abstract : We introduce a finite element method with high-order accuracy for approximating the Vlasov-Poisson system. This method uses continuous Lagrange polynomials as basis functions and employs explicit Runge-Kutta schemes for time discretization. A residual-based artificial viscosity technique is applied for stabilization. READ MORE

  4. 3. Development of a DEM-FEM framework for infrastructure simulations

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Anita Ullrich; [2022-09-20]
    Keywords : ;

    Abstract : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. READ MORE

  5. 4. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Axel Hallén; Jacob Hjorth; [2022]
    Keywords : Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Abstract : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. READ MORE

  6. 5. Additive Design Process for Critical Structures: Attempt study

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Tomas Kassir; Kanthee Prathan; [2022]
    Keywords : Design for Additive Manufacturing; Design Process; Generative Design; Method; Critical Structures; Safety factor.;

    Abstract : There is a gap in scientific knowledge regarding designing functional parts that may not fail, and this project came to define these parts as critical structures. The proposed design process is called the Additive Design Process for Critical Structure, which synthesizes required activities found in the literature review necessary to produce theoretically safe design structures.
